74F582

It seems that the 74F583 is quite similar to the '582 (of course many of the 74TTL series ICs do have near equivalents like this). I too have struggled to find anything on the '582, but a datasheet for Philip's version of the '583 can be found here: http://www.system.perm.ru/escpdf/Philips/74F583_1.pdf, a reasonably good collection of datasheets in Russia. cheers, paul -----Original Message----- From: Dr. Charles E.

Couldn't find a data sheet from Fairchild (who bought National Semiconductor's logic line), Philips, or anyone! Signetics is no longer in the TTL business, I believe. The only things I can come up with are: pspice.metropoliglobal.com/pspice/docs/DIGITAL.PDF ALU 74F582 74F582S TTL 74F582 Octal, with Parity Generator Checker http://www.s-direktnet.de/homepages/sangmeister/daten/ics/icg74.htm NSC 74F582 and: http://www.egm-electronics.com/listen/ic.htm 74F582N SIG 87 DIP I'd be interested to know where anyone does come up with a data sheet. -Charles --
